Large file upload with PHP and NGINX

When trying to upload large files with PHP in an environment which also includes nginx, apart from the php.ini directives of ‘upload_max_filesize’ and ‘post_max_size’, you also need to increase the value of ‘client_max_body_size’ in nginx.conf . See this link for explanation: http://wiki.nginx.org/HttpCoreModule#client_max_body_size
